Abstract

A balloon catheter in which its distal tip is precisely positionable in order to control movement of the catheter through tortuous vasculature and especially through the lumen of a deployed stent is disclosed. The distal tip of the catheter is rendered radiopaque, at least at its distal-most end, to enable visualization of the position of the catheter and to facilitate placing the catheter in the desired position.
